What are advantages of electronic wattmeter?
The advantages of wattmeter include adequate for low frequencies, easy to operate and better technology. There are different types of wattmeter and each has specific advantages.
How you can do Calibration of wattmeter by potentiometer?
221
What are the uses of wattmeter?
Wattmeter is an intrument which is used to measure the power consumption of an Electric circuit or an appliance which is connected to the supply in terms of Watts.
Write down the advantage of 2-wattmeter method instead of 3-wattmeter method for measuring ac power?
It's cheaper.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
How wattmeter dynamometer work?
No
Is wattmeter is work on ac or dc?
this works with both.

What is ac wattmeter?
nothing
What is analog wattmeter?
bungaw..
Can you tell more about electronic wattmeter?
The only type I am familiar with is the Bird 4391M. This a a digital display wattmeter whereas the Bird 43 is an analog (mechanical meter) device. The digital wattmeter has many functions available such as FWD PWR, RFL PWR, MOD, that are selected by front panel push buttons. It is a very versatile unit for measuring RF signal power. The one disadvantage to the digital wattmeter is that it needs to be powered to operate, either on AC line or the rechargeable battery pack. The Bird 43 wattmeter is a very simple unit to operate and requires no external power. You simply plug in the correct element, making sure the arrow on the element points in the same direction as the RF signal flow, apply the RF power and get the meter reading. With both types of wattmeters, the frequency and power range desired to be measured is determined by plug-in elements that go into the front panel of the unit. If using a Bird wattmeter, I would suggest using Bird elements. The ones made by Coaxial Dynamics are good, but the can sometimes cause calibration errors. I have calibrated the Bird wattmeters for many years and they are very durable. You may want to do an internet search on Bird wattmeters for more information on their particular functions. Hope this helps.
Is there any difference in values between the two wattmeter method and three wattmeter method if you apply these two methods in same load?
Blondel's Theorem states that you can have one less wattmeter than there are conductors supplying a balanced or unbalanced load. In either case, the sum of the wattmeter readings will give you the total power of the load.

Will the two-wattmeter method work for all three-phase loads eg unbalanced loads inductive loads capacitive loads and delta-connected loads?
Blondel's Theorem tells us that, to measure the total power of a three-phase load (balanced or unbalanced), we can use one less wattmeter than there are conductors supplying that load.So the two-wattmeter method will work for anythree-phase load, provided there are only threeconductors supplying that load, e.g. three-wire delta or three-wire star (wye).Bear in mind that wattmeter's read true power (expressed in watts) and ignores the reactive power of inductors and capacitors.
